The ALAMO is a San Antonio landmark to remember. It is a former Spanish mission and fortress located in the center of the city. The ALAMO was the site of a pivotal battle during the Texas Revolution in 1836, when a small group of Texan soldiers held off a much larger Mexican army for 13 days before being defeated. The phrase 'Remember the ALAMO' has become a rallying cry for Texans and a symbol of courage and sacrifice.
